But the cylindrical turbine hardly resembled fanlike conventional ones. "Everybody expects it to have propellers," the 52-year-old Watkins said. "People don't recognize it." It not only looked different on the outside, but also on the inside. It lacked the gears that many traditional wind turbines have, he said. Watkins' design transformed the energy from the spinning blades directly into electricity.

In this report we discuss some recent studies that have occurred in the United States since our previous work [2, 3]. The key objectives of these studies were to quantify the physical impacts and costs of wind generation on grid operations and the associated costs. Examples of these costs are (a) committing unneeded generation, (b) allocating more load-following capability to account for wind variability, and (c) allocating more regulation capacity. These are referred to as “ancillary service” costs, and are based on the physical system and operating characteristics and procedures. This topic is covered in more detail by Zavadil et al. .
In a battle over blades and breezes, the county Board of Supervisors on Tuesday tightened rules regulating home wind turbines that produce electricity.
The Los Angeles Department of Water and Power's board passed a contract to acquire a $239-million wind farm in Kern County which is being developed by a private contractor later this year.
This web site provides performance data on wind turbines in California from 1985-2003.
With California's energy crisis in the headlines, advocates of wind power are hoping it will mean a major boost for this source of clean, alternative energy. But they face a previously underappreciated problem: bugs.
